Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, nitrite oxidation to
nitrate, which is an important process of the biogeochemical nitrogen cycle. NOB were …

… However, the detection of H 2 S production by Mycobacterium smegmatis under O 2 limitation
in a mutant lacking all hydrogenases challenges the contribution of group 3b hydrogenase …

… Author links open overlay panel Christopher E Lawson 1 , Sebastian Lücker 2 … As
discussed by Lücker et al. [36 • ], the rTCA is typically employed by anaerobic or microaerophilic …

Nitrification is a two-step process where ammonia is first oxidized to nitrite by ammonia-oxidizing
bacteria and/or archaea, and subsequently to nitrate by nitrite-oxidizing bacteria. …

Nitrospira are barely studied and mostly uncultured nitrite-oxidizing bacteria, which are,
according to molecular data, among the most diverse and widespread nitrifiers in natural …

Nitrogen fixation in the surface ocean impacts global marine nitrogen bioavailability and thus
microbial primary productivity. Until now, cyanobacterial populations have been viewed as …

Marine sponges contain complex bacterial communities of considerable ecological and
biotechnological importance, with many of these organisms postulated to be specific to sponge …

… The spatial arrangement of AOB and GNS in the sludge was quantified by the same approach
after FISH with probes S-*-OTU25to31-1406-aA-18 and Cluster6a192. The results of all …

Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, a major process of
the biogeochemical nitrogen cycle, but the recognized diversity of this guild is surprisingly low …

Nitrospira are a diverse group of nitrite-oxidizing bacteria and among the environmentally
most widespread nitrifiers. However, they remain scarcely studied and mostly uncultured. …
